IMPROVED RUBBER- AND GUTTA-PERGHA Host.

TO ALL WHOM IT MAY concerns;

Be it known that I, EDWIN M. CHAFIEE, of Providence, in the county of Providence, and State ofRhode Island, have inventednew'and useful Impro'iements in Rubber and Gut-ta-Perchn Hose; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification,

in which- The drawing represents a perspective view of a short section of my improved hose.

This invention relates to thc'formation of rubber or gutta-percha hose, whereby thesame is, whcn not distended with water,-madc to occupy less bulk outhe hose-reel or elsewhere.

Heretofore rubber or gutt a-pereha hose maintained its cylindrical or rotuud form at all'times, whether filled with water or not, and therefore was objectionably bulky, filling up the ordinary hose-reels ir'ith hilt a comparatively feiy lengths of hose.

It was also more difiicult to handle.

These objectionable features I obviate by the process of manufacture now to be described, so thutthe above kinds of hose may remain collapsed, and, consequently, as easy to reel up and handle, when not distended, as the common leather 'hose, and also as susceptible of as close pac'hing on then-eel as-the last-named kinds of hose.

The hose, which i s,-in general, made of anynetting of tex tilematerial, cemented togctherin pliesorlayers', i anid'having tbe'extcrior and interior surfaces-of the hose pro-per, when completed, covered or coatcd'with vulcanized rubber or g utta percha, is flattened by exterior plane surfaces, and placed within a heated chamber until the hose has-acquired a permanent flat form, as shown in the drawing. I i

The hose is first made in the usual rotund form, and then placed between long planesurfaccs, which are made -to flatten the hose, and holdit-so flattened, by means of weights, set-s'crews,,clamps, or any suitable mechanical means. i

This flattening of the hose is performed within long chambers, of suilicicntlongitudinal diameter to contain a. single length of hose, and of'sufiicient lateral andvertical dimensions to eont-aina number of suclrlcngths,

side by side, and one above the other, a plane surface being interposed between each superimposed length.

As it is not desirable to permit the complete collapse of the hose, iong strip of metal, wood, or webbing, is inserted in each length of hose,whiclrprevents the complete collapse of the hosc," audthereby conduees to a more symmetrical appearance to the flattened hosed i I i i The hose-chan1bcr is then' heated internally, by means of steam-pipes along, its interior sides;'or hot air or water may beinjeeted at large, or forced within the chamber, for the same purpose; or', if more desirable,

the flattening-planes before described (which should he of metal) maybe the exterior surfaces of hollow plates,

containing hot steam.

The hose may be treated as above described, before or after complete vulcanization but I prefer to take the unvulcanized rotund hose, and submit it to the heat of vulcanizn -on between the flattening-planes, as

.aboye described.

When hose, vulcanized or unvulcaui zed, is flattened by pressure, and submitted to heat, as above stated, it will, when cooled, retain its flattened form, which is superior to tlrerotun'd form, for the reasons mentioned. The hose having been originally formed with a circular section, the plies or layers of tcxtile matcrial,

com osin the bed of the hose are'in such correlation-to each other as to take c uall Y the strain of disten- P g y 1 tion when ,water is forced through, for the ilattening' process does appreciably alter the original relation of the plies. i i l i This treatment of hose isnot expensive, and, if itis madeto form part of the rulcanizin treatment, the expense of flattening the hose will be scarcely more than the first cost of the flattening-plates.

I claim as new, and desire to secure by Letters Patent- The rubber'or guttwpercha hose, flattened be'twccn plane surfaces, uiider the heat of \"ulcan'ization,sub-- stantially as described, for the purpose specified. n
